Frequently Asked Questions

What are the main concerns with mounting optics on a Gen 6 Glock?

Concerns include the optic mounting system potentially having play until screws are tightened, the reliance on optic manufacturer screws (not Glock's), and the Gen 5 MOS system being considered a failure, suggesting potential issues carried over or addressed in Gen 6. Proper use of spacers and torque is crucial.

How does the Gen 6 Glock grip and recoil compare to the Gen 5?

The Gen 6 Glock grip is perceived as smaller in diameter, potentially offering less room for the support hand. Its recoil impulse is described as slower and softer than that of the Gen 5 Glock, contributing to a different shooting experience.

What aftermarket parts are mentioned for Gen 6 Glocks?

The video mentions brass butt plugs from S Shooting Sports Innovations and reduced power striker springs from ISMI (4.5 lb and 5 lb) which can slightly alter the trigger pull weight. CH Precision is also referenced.

What is the recommended procedure for mounting an optic on a Gen 6 Glock?

Always follow the optic manufacturer's instructions for screw size and torque, as Glock's MOS system defers to them. Ensure any spacers or gaskets are correctly placed and tighten screws sufficiently to eliminate play and securely seat the optic.
